STEEL MINE GAR.

, A CORPORATION OF NEW Application filed January 24., 1925. Serial No, 4,515.

To (ZZZ whom it may concern:

Be it known that 1, JAMES B. /Vonr, residing at Glen Ridge, Essex County, New

Jersey, and being a citizen of the United States, have invented certain newand useful Improvements in a Steel Mine Car of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention; though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications therebf within the scopeof the claims will occur to persons skilled in the art.

in said drawings:

Figure 1 is a view showing the improved mine car partially in side elevation and partially in longitudinal section;

Figure 2 is a view showing the mine car in top plan with one end portion shown in longitudinal section;

Figure 3 is a transverse sectional View;

taken along the line 33 of Figure 2; and

Figure 4 is a fragmentary view of the brake operating mechanism.

An object of this invention is to provide a mine car having an improved body construction which includes a bottom so constructed that brake operating means may be mounted in an improved manner and to permit the wheels being mounted upon axles positioned close to the bottom of the car and the wheels protected by hoods carried by the bottom of the car. I

Another object of the invention is to so construct the bottom of this car that a longitudinally extending housing will be provided which is open at its lower side and will serve as a housing for the car couplers and also as a housing for a longitudinally extending shaft forming part of the brake operating mechanism.

Another ob ect of the invention is to so construct this car body that the journal boxes of the wheel carrying axles may be mounted by means of pedestals extending up into the car and having the wheel protecting hoods connected with their upwardly protruding portions and further having their upwardly protruding portions secured to the side walls of the car.

, and the chords.

Another object of the invention is vide the car with an improved wall construction which will be very strong and at the same time of a simple construction.

'lh1s improved mine car is provided with a body portion having a bottom or flooring 1 formed of longitudinally extending floor boards, and side and end walls 2 and 3.. These side walls are provided with upper and lower chords 4 and 5 which are formed of angle iron and are held in the proper spaced relation by posts 6 which are also formed of angle iron and serve not only as means for retaining the chords in the proper spaced relation but also serve as means for assisting in retaining the wall sheets against the inner faces of the chords. These wall sheets 7 are formed of heavy sheet metal and from an inspection of Figures 1 and 2 it will be seen that the sheets are secured against the inner faces of the chords by rivets 8 and that similar rivets are also provided to secure the posts inplace with the sheets 7 firmly held between the posts a The corner posts 9 in addition to retaining the chords 4 and 5 in proper spaced relation also serve as means for connecting the end walls with the side walls and as additional means for bracing the walls there have been provided bracing plates 10 which are secured upon the outwardly extending flanges of the upper chords l and to the outwardly extending flanges of the upper chords 11 of the end walls. "It is not necessary to provide the end walls with lowerchords as the sills 12 take the place of lower chords and the wall sheets and posts 13 of the end walls will be secured to the outer depending side flanges of the sills 12 by rivets or other suitable fasteners.

The flooring which is formed of longitudinally extending floor boards has its boards secured at their ends to the sills 12 by fasteners 14- and these-boards are also secured by suitable fasteners to the up er flanges of the cross beams 15 and 16 which extend beneath the flooring and are secured to the lower chords of the side walls. Between the cross beams 15 and 16 the floor boards forming the side,portions of the flooring have been removed so as to provide openings in the side portions of the car and to pro Y intermediate the length thereof. It should the flooring.

vided with a longitudinally disposed open space intermediate its width and that a sheet metal housing 17 which is U-shaped in cross section is projected upwardly into the car through'this open space and is held in place by flanges 18 which engage the bottom of These flanges are engaged by the cross beams 15-16 and by the sills 12 so that the housing will be very firmly held in place. It should be also noted that there have been provided collars 19 which fit about the end portions of the housing within the car and are secured to the housing and to' the end walls. This housing is adapted to receive the draft means and also serves as a housing for a portion of the brake structure to be hereinafter described.

The draft means consists of the couplers 20 one of which will be provided at each end of the car. Each of these couplers extends inwardly through an'opening formed in the end wall and rests upon the sill 12. The inner end of the coupler rests upon a supporting plate 21 which extends transversely beneath the housing as shown in Figure 1 and a pin or bar 22 extends from the inner end of the coupler and through an abut-- ment 23. A spring 24 is mounted upon this bar 22 between the abutment 23 and the inner end of the coupler so that the coupler will be yieldably held against inward sliding movement and a securing nut 25 is pro vided so that the bar 22 may be limited in its outward movement and the tension of the spring 24 controlled by adjustment of this nut.

The axles 26 extend transversely beneath the car body and have their inner portions journaled in journal boxes 27 which are mounted infpedestals 28 and engaged by the springs 29 which are positioned between the 'ournal boxes and the upper end portions of the pedestals as shown in Figures 1 and 3. These pedestals are secured to the cross beams 15 and 16 by suitable fasteners 30 and have their upper end portions extending through the openings in the flooring of the car. Referring to Figure 3 it will be seen that the pedestals are positioned in close contact with the wall sheets 7 of the side walls and that fastener bolts 31 are passed through the wall sheets and upwardly arched portions 5 of the lower chords 5 so that the pedestals will be firmly anchored to these lower chords. This provides a very strong construction and at the same time permits the pedestals to be easily removed when necessary. The wheels 32 which are carried by the axles 26 extend upwardly through the openings in the flooring and in order to protect these wheels and prevent material from passing through there have been provided hoods 33 which are secured to the inwardly extending side flanges 34 of the pedestals and to the floor the openings ijtdaiao and 3 it will be seen that the hoods have outstanding flanges 35 which are secured against the under face of the flooring by suitable fasteners and that when the pedestals and hoods are in place the openings formed in the flooring will be completely filled. Therefore the journal boxes, springs and wheels will be protected from damage as the material in the car cannot leak out through these openings. This will also of course prevent loss of material placed in the car.

The brakes 36 are suspended from the cross beams 16 by hangers 37 so that they may have movement towards and away from the wheels and these brakes are connected with arms 38 which are carried by the pins 39 at the ends of the brake beam 40. This brake beam 40 extends transversely beneath the car and passes through straps 41 which serve to guide and limit vertical sliding movement of the brake beam. A link 42 is pivotally connected with the brake beam between the straps 41 and extends upwardly into the housing 17 with its upper end pivotally connected with the arm. 43 extending transversely from the shaft 44. This shaft 44 extends longitudinally in the housing and is journaled in bearing brackets 45 secured to a side wall of the housing 17 and has itsouter end portion extending through an opening formed in the end wall at one end of the car. This shaft 44 extends above the coupler as shown in Figure 1 and therefore it will not interfere with operation of the coupler. The extended outer end of this shaft is squared as shown at 46 in Figure 4 and carries an operating lever 47 which extends upwardly from the shaft and carries a tooth 48 for engagement with the rack 49. This rack extends transversely of the end wall and is secured with its major portion in spaced relation to the end wall. It will thus be seen that the lever may be swung to rotate the shaft and operate the brakes and that when moved to apply the brakes the lever may be securely held in a set position by engagement of the tooth 48 with the rack. Ordinarily this lever will, be retained in the position shown in Figure 3 by the hook 49 carried by the short chain 50 and when in this position the brakes will be in an inoperative position.
